Abstract

La présente invention concerne des systèmes, des procédés et des appareils permettant le transfert d'énergie sans fil, et en particulier le transfert d'énergie sans fil vers des systèmes distants, par exemple des véhicules électriques. Selon un aspect, l'invention concerne un appareil destiné à être utilisé avec un dispositif émetteur de transfert d'énergie sans fil comprenant un premier élément inductif générant un champ magnétique. L'appareil comprend une première source d'alimentation en courant continu (CC) dont la tension de sortie est ajustable. L'appareil comprend également un onduleur configuré pour convertir la tension de sortie de la source d'alimentation en courant CC en un courant alternatif. L'appareil comprend également au moins un dispositif de commande configuré pour recevoir une indication sur le courant dans le premier élément inductif et commander la tension de sortie de la source d'alimentation en courant CC en réponse à l'indication sur le courant dans le premier élément inductif. L'appareil réduit les signaux de distorsion dans la sortie de courant alternatif de l'onduleur tout en maintenant le courant sensiblement constant dans l'élément inductif.
